The truck had been parked for about 4 hours, after a 250 mile trip. I cranked it and started driving to return home. I heard an intermittent squealing noise while driving. I had driven only about 2 miles when the engine suddenly shut down in heavy traffic on a four lane divided highway. I managed to get the truck into the median and stop. I was left stranded in the middle of the highway. It turns out the the engine bearing went bad and ruined the engine. I will now have to replace the engine at a cost of about $15,000.00. This is a safety concern when the engine suddenly failed and stalled while driving on a four lane divided highway, in heavy traffic.
Engine failure. Cam bearings failure. Engine seized up. Safety issue: traveling on highway towing a fishing boat. Pulled off for fuel. Engine completely seized up while at gas pump. If it had it seized up before pulling off highway for gas, great risk for a catastrophic crash, especially when pulling a boat trailer. All systems including steering shut down. John jones chevrolet dealership in scottsburg indiana ran diagnostics and confirmed complete engine failure. Faulty cam bearings seized up. Engine is ruined and must be replaced. Inspection by john jones chevrolet dealership. We had been on the highway for 3.5 hours when pulled off for gas. There were no warning signs. No check engine lights, no lights at all on the dash. No unusual sounds or smoke. Nothing unusual before the engine seized up.
valve train/camshaft fairlure which damaged entire engine - happened at 99,650 miles
The passenger side lifters in my truck failed while at idle/5mph speed causing catastrophic engine failure. 2019 6.2L V8 from GM. From my own independent research, and the research/survey of others online, this appears to be a very common problem as a result of known defective parts that were installed on GM engines.
Lifters in engine failed at beginning of March 2025 and destroyed inside of engine. Transmission failed in summer of 2024 and had to be replaced
I was driving down [XXX] near Harrisburg PA in an active construction zone when the truck shut off, the dash blinked a few things very rapidly then went black. I was barely able to coast to an area large enough to get my truck out of the highway traffic. I was stranded on the side of the highway for 4 hrs and due to the construction hardly able to get out of the truck safely as it was around a bend. I’ve had to have the truck towed to a few mechanics to learn that it has suffered a catastrophic engine failure as all cylinders have lost compression. It made no noise at all. There was no signs this was going to happen, just driving normally then a complete engine failure resulting in no compression in all 8 cylinders with no noise.

While attempting to accelerate to get onto the expressway with no warning, the vehicle went into limp mode. Traction control, front end warning collision, auto/stop start functionality was all disabled and the engine light warning light on came on. The vehicle locked out and reduced acceleration. An attempt to pull over and turn the vehicle off for a few seconds was made. Once restarted, the vehicle continued running on limp mode at reduced speeds with the same indicators mentioned still disabled and locked out.
It blew a hole through the engine block. The engine is a 6.2 L 87
Cylinder 5 failure and cam shaft miles 78k. Have to replace full top end or brand new motor cost $10k up to $13k to fix at dealer
I was traveling north on interstate 95 and approaching my exit ramp. I was initially in the inside lane of travel. I accelerated to merge into the outside lane, between two other vehicles, and then onto the exit ramp. Once on the exit ramp, I let off of the throttle and the engine suddenly shut down. I noticed a message on driver information center instructing me to shift the vehicle into neutral and press "start again". The engine had shut down without any warning whatsoever. I complied with the instructions to no avail. The truck is over half full of fuel. I was within an hour of home after completing an approximately 8 hour, 500 mile, round trip over 2 days of driving. After this event, I connected an OBD2 scanner and the only code found was P25A2 brake system control module. I placed the truck in park and tried repeatedly to start the engine. It would not turn over, crank or start. I had power to all systems and no other codes. I had to have the truck towed from the scene. The truck's performance had previously been flawless during this entire trip and had given me no warning whatsoever of the sudden engine shutdown. This is extremely dangerous and a safety concern.
Driving on the highway, while accelerating, heard a mechanical failure from the front end of the vehicle and had immediate loss of power, and reduction in performance/handling. The engine light came on and three warning messages; Service ESC, Service Parking Brake & Steering Assist is Reduced Drive with Care. Fortunately, the local GMC dealer was the next exit which is where the truck is currently located. The truck was inspected by the dealer and determined the engine should be replaced. It is available for inspection upon request. I have pictures of the warning messages and the work order from the dealer of their findings to date.
While driving at 65 mph on a freeway, the engine failed and cracked a rod with fresh oil and all maintenance done regularly. Truck brakes would not work after engine failure. Truck was fully disabled and I was stranded on freeway @ 90,000 miles. Lights on exterior of the vehicle were dim after engine failed
This morning, while driving to work, my truck was operating smoothly without any prior warning signs. Suddenly, the dashboard displayed a message indicating "Low Oil Pressure" and instructed me to turn off the vehicle. There were no preceding alerts, such as check engine lights or low oil pressure indicators. As I was preparing to follow the instructions, the vehicle dashboard displayed another message directing me to put the truck in neutral, and then the engine automatically shut off. Unfortunately, after this occurred, I was unable to restart the truck.
I was driving to work on Saturday morning [XXX]. As I pulled out of the stop sign and approached 45 mph the engine stop. Making me a hazard within the road. I had to abruptly pull off into a road/yard in order to be safe. All while not having a power as the engine completely stopped. Upon investigation the dealership, Budd Baer in Washington Pennsylvania confirmed the engine had seized up due an issue in rotating assembly.

Engine failure. Lifters failed causing internal engine damage. No previous warning. 160000 miles. Repair cost is $5000
cylinder #1 had misfire and this was because the liftt malfunctioned which inturn caused it to grind on camshaft
Engine threw a rod and needed to be replaced out of pocket due to vehicle being out of warranty. Going down I35 so not safe at all. All dash light illuminated when it occurred.
Lifters are failing which could cause motor shutdown during driving.11/26/2024
Unknown mostly. Water pump ended up cracking while running. Power failure notice had come up on dash and then vehicle shut off while running. Dealership made repairs but unable to identify root cause.
while driving down the road i noticed the truck had a lack of power and then the check engine light came on and as soon as it came on i heard a ticking/clacking noise. I got the truck towed to a repair facility and they found misfire on cylinder 8, they informed me and wanted to drain the oil and also removed the valve cover in order to check the valve train. They found a lot of metal in the oil along with a decent amount of decent shavings in the oil filter. They removed the valve cover and found a bent pushrod and stuck lifter. They did mention a possible noise coming from the bottom end of the engine (knocking) but at this time with the amount of contaminates in the oil and stuck lifter, The engine is recommended to be replaced. No ETA at this time for a replacement
Engine seized it won’t crank we swapped the alternator 2 times the battery once the and the starter once we also swapped the battery chip 3 times and it would turn off out of no where. We thought it was because of the miles but it was working fine. And took care of it nicely. We took it to a dealership and they told us that it needed a new motor because it was seized. But before that it would start up and turn off after 15 minutes. We took it somewhere else in a tow truck and they told us that the engine was seized.
On Jan 7, 2024, we went to Walmart to shop (DeRidder, LA). The truck was running normal. All gauges were normal and the reason I can say this is because our truck broke down in 2023, so we have a habit of checking them when we start the truck before driving and during driving periodically. When leaving Walmart we were at the red light and the truck just stopped. A message came on and said to shift into Neutral, which we did. The truck then died and would not stop. Pushed it into the parking lot and had it towed to Billy Navarre Chevrolet, Lake Charles, LA. After they looked at the truck on Jan 9, they said the engine was seized and we needed a new one. They couldn't say why. They said that would be figured out when the old motor was shipped back. After putting in the new motor, the POC at the dealership called and said we needed a new water pump that the one he took off was bad. They insinuated that was the cause of the engine seizing. However this wasn't determined until they went to put the old one on. If the water pump failed, we believe it should have started showing engine overheat and there was no such thing.
Complete engine failure. Absolutely insane. All lights on dash, engine seized while driving!!!!!!!!!!!!!! Unbelievable that GMC keeps making us fix issues and pay for it! They won't cover the cost. This has been happening too much and putting my family at risk!
Engine failure- sent in old engine as a core piston broke off the rod causing the engine to seize replacing with reman engine from GM
Driving home on a rural two-lane road the engine started make a load banging noise on the drivers side, than it started to skip and not running on eight cylinders. it than lost oil pressure.
I was driving down the highway with my teen daughter heading to a hockey tournament in Michigan. We live in Illinois. While in Michigan on the highway driving around 80 mph, I went to pass a vehicle and several service warning lights starting flashing on the dashboard. The ones that flashed were: Service ESC, Service Parking Break, Steering Assist is Reduced Drive with Care. At the time, the engine started making rattling noises and sounded rough. I could feel there was a problem right away. I carefully pulled over and turned the truck off. I waited a few minutes and then turned the truck back on. The service warning lights were still on and the engine was still running and sounding rough. I tried turning it off and on again but the same problem persisted. I then drove the truck about one mile to the next exit just to get off the highway. I was doing about 45mph during this time. I then pulled into a parking lot and contacted On Star to diagnosis the vehicle. They diagnosed a P300 code and said it was an engine misfire. I then found a local repair show and drove another 2 miles to get there. They looked at it for an hour and said they could not help me. They were also getting the cylinder misfire code. I had the vehicle towed to a dealership that same day. I had to rent a car to return back to Illinois with my daughter. After a week and a half, the dealer started looking into the issue. They diagnosed a lifter failure and said a new engine was needed. We purchased the new engine for $10,490 and the dealer installed it. Three weeks later, the vehicle was ready and we had to drive to Michigan to pick it up. I’ve reached out to GM and they just apologized and offered us 15,000 points in our GM account. We declined. We asked for financial assistance and they also declined and said it was out of warranty and it’s our responsibility to pay for all costs.
